I was in a pinch and needed to get my computer hardware setup asap. David came out-- on a holiday weekend, no less-- and got me up and running in no time. I appreciate his friendliness and enjoyed our conversation about various IT topics. David knows his stuff! I highly recommend him!

Great Guy. Real professional. Responds quick and can work at your place or remotely, to fit whatever problems you have with computers. I had issues with my new gaming pc, I messaged David late at night by the time I woke up he responded and was willing to travel to me to solve my Pc problem. Again above all he’s a great dude and fun to work with truly. Thank you again David

THE BEST. Oh my goodness. I had a Dell 7760 problem where my computer was going to sleep every few minutes. It was driving me crazy and making my beloved PC laptop unusable. David called me and fixed a problem I had been living with for months, David logged in my PC and fixed the entire problem in less than three (3) minutes. True story. I am still sort of blown away by his knowledge and he's also a very patient, really nice person! Do not EVER hesitate to call David. You just don't get value like this anymore.

Dave K./ADHERE SYSTEMS owner was great! Top recommendation. Dave's work installing a new desktop+ monitor+ all-in-one was very efficient, and there were problems with my important but aging backup drives, some of which needed rescuing, from way back to WIN XP - 10. Dave is a pro: he recovered just about everything, going back 15 years. I had lost so many important Docs files due to MS evil ONEDRIVE disrupting hundreds of backup attempts, that my online life required a serious, well, intervention. Thanks for righteous, thorough work, Dave.
